2.6.183 TPTFAIL (G-Series)

•Major (MJ), Service Affecting (SA)

The Transport (TPT) Layer Failure alarm for the G-series Ethernet (traffic) cards indicates a break in the end-to-end Ethernet link integrity feature of the G1000-2 cards. TPTFAIL indicates a far-end condition and not a problem with the port reporting TPTFAIL.

The TPTFAIL alarm indicates a problem on either the SONET path or the remote Ethernet port that prevents the complete end-to-end Ethernet path from working. If any SONET path alarms such as an AIS-P condition (see page 2-17), an LOP-P alarm (see page 2-80), a PDI-P alarm (see page 2-93), or an UNEQ-P alarm (see page 2-122)exist on the SONET path used by the Ethernet port, the affected port causes a TPTFAIL alarm. Also, if the far-end G1000-2 Ethernet port is administratively disabled or it is reporting a CARLOSS (G Series) alarm (see page 2-33), the C2 byte in the SONET path overhead indicates a PDI-P alarm (see page 2-93)which in turn causes a TPTFAIL to be reported against the near-end port.

When a TPTFAIL alarm occurs, the near-end port is automatically disabled (transmit laser turned off). In turn the laser shutoff can also cause the external Ethernet device attached at the near end to detect a link down and turn off its transmitter. This also causes a CARLOSS condition to occur on the reporting port. In all cases the source problem is either in the SONET path being used by the G1000-2 port or the far- end G1000-2 port to which it is mapped.

Procedure: Clear the TPTFAIL (G-Series) Alarm

Step 1 An occurrence of TPTFAIL on a G1000-2 port indicates either a problem with the SONET path that the port is using or with the far-end G1000-2 port that is mapped to the port. Clear any alarms being reported by the OC-N card on the G1000-2 circuit.

Step 2 If no alarms are reported by the OC-N card, or if a PDI-P alarm (see page 2-93)is reported, the problem might be on the far-end G1000-2 port. Clear any alarms, such as CARLOSS, reported against the far-end port or card.

Step 3 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).

2.6.184 TRMT

•Major (MJ), Service Affecting (SA)

A Missing Transmitter (TRMT) alarm occurs when there is a transmit failure on the XTC-14 card because of an internal hardware failure. The card must be replaced.
